Digital Vortex Flow Meter (DVFM)

Summary : Modern digital signal processing method used in the vortex flow detection technology, Breaking the traditional analog method of processing the limitations of vortex signal. Clearly overcome low flow detection sensor to detect the weak signal problem, effectively eliminating the flow of noise, greatly improved the vortex of anti-vibration performance, a fundamental solution to the troubled years of the Development of vortex detection problems so revolutionary. Modern digital signal processing by the latest technology to vortex probe signal to analyze, filter, transform, and thus correctly filter out the right flow signal, accurate, reliable measurement data. Intelligent digital vortex Flow meter can be adaptive of various pipeline, measuring medium, the use of the environment. With: Lower measurement limit, wider detection Range, higher measurement accuracy, superior anti-jamming and anti-seismic performance. Free commissioning, free maintenance.Feature
